Abstract

A method and apparatus for providing an integrating sphere for use as a measuring device is described. More specifically, the integrating sphere includes a generally spherical shell and a liner disposed within said generally spherical shell, wherein the liner is composed of a sintered polymer. In one embodiment, the liner is made up of a pre-formed polytetrafluoroethylene (PTFE) shell.
